Sheet Assistant

Describe what you want your Google Sheet to look like — not just what it should do. Most people know their data but aren't designers, and it shows: cramped columns, default colors, no consistent style. Sheet Assistant generates the ready-to-run Apps Script for a clean, professionally styled sheet, using your own Claude API key. Nothing shared with Alpray, nothing runs until you paste it in yourself.

Build your script

Don't have one? Create a key at console.anthropic.com/settings/keys.

Your key is stored only in your browser (localStorage) and sent directly to Anthropic's API to generate your script — it is never sent to or stored by Alpray.

Frequently asked questions

I'm not a designer — will this actually make my sheet look good?

Yes. Sheet Assistant applies consistent color rules, spacing, and header styling by default — a small fixed palette, reserved colors for status (good/warning/critical), one hue for magnitude shading, and clean borders — so you don't have to make those design decisions yourself.

Do I need my own Claude API key to use Sheet Assistant?

Yes. Sheet Assistant is a bring-your-own-key tool — you paste in your own Anthropic Claude API key, which is used to generate the Apps Script code. You can create a key at console.anthropic.com/settings/keys.

Is my API key ever sent to Alpray?

No. Your API key is stored only in your own browser's local storage and sent directly to Anthropic's API. Alpray's servers never see it — there is no backend involved.

Do I need to share my Google Sheet with Alpray?

No. Sheet Assistant only generates code based on your description. You copy the code and paste it into your own Google Sheet's Apps Script editor and run it yourself — nothing is uploaded or shared.

What if the generated script doesn't work or throws an error?

Always review generated code before running it. If it references columns or tabs that don't match your sheet, add more detail to the "Current Sheet Structure" field and regenerate — the more specific your inputs, the more accurate the output.

Sheet Assistant runs entirely in your browser using your own Anthropic Claude API key. Alpray does not receive, store, or process your API key, your inputs, or the generated code.
